Application filed September 9. 1914. Serial No. 860,881. j

To all whom it mayconcern:

Be it known that I, MARTIN L. (inovn, a

. citizen of the United States, residing at Tylersburg, in the county of "Clarion and State of Pennsylvania, have invented a new and useful Gasolene-Strainer, of'ivhich the following is a specification. 7

The invention relates to improvements in gasolene strainers.

The object of he present inventing;- is to improve the construction of gasolene,. strain- .ers and to provide a SlIIlPlQf practical, and

I its position in the pipe.

ith these and other objects in View the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims appended hereto, it bein understood that various changes inthe orm, proportion, size and minor details of construction, .within the scope of the claims, may beresorted to without departing from the spirit or sacrifici'ng any of the advantages of the invention.

In the drawingp-Figure 1 isasidc elevation of a gasolene strainer constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 is a central transverse sectional view of the'str'ainer. Fig. 4: is a detail secs f tional view of the cap nut, illustrating the arrangement of the filtering material.

Like numerals of reference designate core responding parts in all the figures the 46 drawing.

In the accompanyin drawing, in which i is illustrated .ihe preferred embodiment of the invention, 1 designates a horizontal tubular body or casing of substantially cylindrical form. ppen at one end 2 and.provided. at the other end with an integral end wall 3 having a threaded ,opening'd, preferably, in the form of a adapted to receive an inlet pipe nipple, as shown, and The body or casing 1 is provided at an intermediate pointwith a depending downwardly tapered trap extension (Shaving asubstantially cylindrical lower terminal port1on 7 which is interiorly threaded at 8 for the reception of-a. removable screw plug 9.

The screw plug" 9, which is threaded at 10 to engage the threads of the trap extension, is provided with annular flange 11, and it. has a sqpared'wrnch receiving portion'12. The flangell Iits'againSt the lower edge of the trap extension and the plug is provided" at the top with a recess or concavity 13,

adapted to lighten the structure and at the same time form a cup for holding the impurities accumulating within the trap extension. The open end 2 of the casing is interiorly threaded for the reception of an cxteriorly threaded portion 13 of ahollow cap nut 14, provided with a central threaded opening 15, preferably in the form of a threaded nipple, and arranged in horizontal, 'alinem'ent with the threaded opening 4 and receiving the threaded end 15 of an outlet pipe 16.v As the threaded openings of the end wall 3 and the cap nut 14 are in hori' zontal alinement, the strainer is adapted to be readily applied to various types of auto mobiles and other motor vehicles.

The hollownut is provided with a plurality of interior annular recesses 17 and 18 of different diameters forming shoulders or seats 19 and 20. The recess 18 is arranged in spaced relation with the end wall of the cap nut-to provide an annular space '21,

which is of less diameter than the recess 18.,

The space 21 is adapted to containa quantity of free gasolene or other liquid and it insures a proper supply for the same and at the'same time permits free action of the device in straining the gasolene. The shoulannular groove 25 in the'walls of the recess 17. The retaining ring; which is .consh-ucted of a single piece oi resilient wlre or other suitable material separated at its ends 26, as clearly illustrated in Fig. 3'of5the drawing. ,isadapted to be readily; sprung into and out of engagement with the groove, and it engages the screen andsecurely holds the same and the chamois-straining diskfon the shoulder or seat 1 The screen 23, which is constructed of wo en wire, is adapted to strain the impurities from the gasolene, and, withfthe 'cha'mois disk, is capable of separating the water and sediment. The recess 18 is provided for the purpose of enabling any other suitable additional filtering material, as shown at 28 in Fig. {of the drawing, to-be employed and to beretained in place by the fastening means for securing thescreen.

and wateie from gasoleng it. may be em-. ployed for other purposes; and the packmg receiving recess or; space jl1avill enable the proper filtering material to-be placed in the cap nut for adaptihg the device for any desireduse. The combined cup and closure plug 9 is adaptedto catch and retain the sediment and i1npuritie's, 'and when removing the plug, such accumulation maybe re- 'tained in the recess while the liquid may be caught in, a suitable receptacle placed beneath thecasing. The pipes 5 and 16, with which the 'casing is connected, are provided with suitable unions 2 for enabling the or out of position.

from the pipe line.

The invention above set forth is distinguished from prior constructions in at least two particulars. First, it will be noted uponreference to Fig. 4 that the filtering Tam aware that it is old in filters to provide stepped screens and this I' do not broadly claim. The novelty of this part of. .the present invention resides in the fact that by reason of the position of the parts and 28 with relation to the retaining "ringthe latter :-.(|."\'CS to hold said three parts in position within the cap.

' The second feature resides in the location of the filtering medium in a capprovided at the outlet end of the casing so that it is not necessary to remove the casing when it It can be' is desired to clean the strainer.

' readily seen that the cap 1%, which is in the form of a hollow nut, may be readily un-.

screwed from the casing without detachingthe other end ofthe casing from the pipe line, or without separating the casing itself from its position inthe. line of piping be tween the gasolene tank and the carbureter. By applying a wrench to the hollow rap nut 14, the latter maybe unscrewed from the casing without disturbing any of the other parts of the casing. This made possible by-reason of the fact that a union-joint connects the short section of the pipe 16 with the adjacent end of the pipe line. Moreover, when the hollow cap nut is removed,

the. cap, is in it carries with it the straining and filtering medium intact, and yet it takes but a moment to remove the filtering material, straining disk and" the screen from their rcspective positions within the cap nut after the retaining ring has been detached. An;

'ther advantage in having the straining n'd filtering medium applied to the hollow cjapinlut lies in the fact thatshould large chunks of dirt pass through the inlet pipe 5 they will not reach ,the screens but will gravitate to the bottom of the casing by reason: of the positionof the depending trap extension 6, and may then 'be removed through the screw plug 9. There is therefore a clear advantage in" providing the straining and filtering medium in the hollow cap nut in the manner herein described and shown.

What is claimed is 1.
